The reasoning behind it is that the ODST armor can't track two weapons at once. Which, really, is total bull-blam!- if we get to use the ODST helmet and still can dual wield. Oh, really, though, it's the fact that I can pick up a Plasma Rifle and a SMG and leave people staring at their TVs going, "What...?" i.e., shield defeating measures aren't going to make the game fair when you've already got a lack-there-of shielding systems, and a bunch of enemies have shields. Oh, wait a minute, that's not fair
